Directions:

Reduce heat to medium-low; add shallots. Cook, stirring frequently, until softened, about 2-3 minutes; add a few handfuls of kale, tossing with tongs and adding more as it cooks down, until kale is tender, 3-5 minutes. (If skillet seems dry while kale is cooking, add a splash of water.)

In a large bowl, whisk together eggs, egg whites, cooked bacon, feta and salt; pour over kale mixture. Stir to evenly distribute ingredients; cook undisturbed until eggs are set, about 3-5 minutes.
